Abstract
The utility model discloses a rivet block for the rivet head of a chain pin shaft, which comprises a pin shaft, an outer chain plate and an inner chain plate, wherein the pin shaft connects with outer chain plate to form an outer chain link, a sleeve is arranged on the external of the pin shaft, and the sleeve and the inner chain plate form an inner link which is in splicing connection with the outer chain link. A circular head sheet is arranged on the pin shaft, and an upper rivet block and a lower rivet block are arranged on both ends of the pin shaft. The lower surface of the upper rivet block contacts with the circular head sheet, and the upper surface of the lower rivet block contacts with the outer chain plate. The rivet block has an additional function for leveling circular head sheet, so that no encased knot or floating sheet may occur, and the appearance quality of finished annular chains can be effectively improved.
Description
Technical field
The utility model relates to a kind of riveting piece, what be specifically related to is the riveting piece that a kind of chain hinge pin die is used.
Background technique
After the bundled production of existing chain, the outer plate of the chain of in bundling is depressed the degree of depth by the unified control of assembly line, and the upper and lower die of bearing pin also is one step completed by the roll riveting machine.The point riveting is after will encircle head place's chain link and interconnect by bearing pin back formation expansion die to be beaten by riveting in the termination of bearing pin to make the chain sheet can not break away from bearing pin.
Prior art has a common shortcoming when being exactly a some riveting, and upper and lower riveting piece only has the effect that presses to bearing pin, a ring sheet do not had certain restriction, the ring sheet depress the degree of depth and other chain link outer plate degree of depth are inconsistent, so the phenomenon of fast knot or floating sheet appears in the chain link at a ring sheet place easily, influenced the appearance quality of finished product chain.
The model utility content
At the deficiency that exists on the prior art, the utility model purpose be to provide a kind of can planarization ring head sheet, reduce the riveting piece that the chain hinge pin die of frock consumption is used, simple and easy to do, reduced the leveling operation, saved cost of production, improved quality of product.
To achieve these goals, the utility model is to realize by the following technical solutions:
The riveting piece that a kind of chain hinge pin die is used, comprise bearing pin, outer plate and inner plate, bearing pin connects to form outer link by outer plate, bearing pin is provided with sleeve outward, sleeve and inner plate connect to form inner link, inner link and outer link are pegged graft, on bearing pin, be provided with a ring sheet, be respectively equipped with riveting piece and following riveting piece at the upper/lower terminal of bearing pin, the lower surface of last riveting piece contacts with a ring sheet, the upper surface of following riveting piece contacts with outer plate, and the upper and lower riveting piece leveling degree of depth depends on riveting piece opening size size, the bearing pin degree of depth and the riveting piece size that presses of appearing.
Upper and lower riveting piece contacts with a ring sheet and outer plate respectively, the degree of depth unanimity of the feasible back ring sheet that presses, and a ring sheet is unlikely to occur dying for the sake of honour or floating sheet phenomenon, has increased the appearance quality of finished product chain, has alleviated operator's labor intensity.
Upper and lower riveting piece of the present utility model has increased the function of planarization ring head sheet, the lower surface of last riveting piece contacts with a ring sheet, the upper surface of following riveting piece contacts with outer plate, control ring head sheet that can be correct depress the degree of depth, be unlikely to occur dying for the sake of honour or floating sheet phenomenon, effectively improved the appearance quality of chain.After pressing, the increasing of die area of contact has reduced part consumption, has played the effect of getting twice the result with half the effort.This purpose is improved also can apply with the craft point of various chains and is riveted over.Reduce working strength of workers, improved quality of product.The simple and easy to do leveling operation that reduced has been saved frock consumption and a large amount of labor hour.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the plan view of riveting piece on the utility model;
Fig. 3 is the side view of riveting piece on the utility model;
Fig. 4 is the structural representation of finished product chain of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
Referring to Fig. 1, Fig. 2, Fig. 3, the utility model comprises bearing pin 1, outer plate 2 and inner plate 4, and bearing pin 1 connects to form outer link by outer plate 2, the bearing pin 1 outer sleeve 3 that is provided with, sleeve and inner plate 4 connect to form inner link, after inner link and outer link are pegged graft, are provided with a ring sheet 5 on bearing pin 1.
Riveting piece 6 and following riveting piece 7 on the two ends of bearing pin 1 have respectively, the lower surface of last riveting piece 6 contacts with a ring sheet 5, and the upper surface of following riveting piece 7 contacts with outer plate 2.Last riveting piece 6 and down the leveling degree of depth of riveting piece 7 depend on riveting piece opening size size and bearing pin 1 degree of depth and the riveting piece size that presses of appearing.Make to be unlikely to the degree of depth unanimity of encircling a sheet 5 to occur dying for the sake of honour or floating sheet phenomenon, increased the appearance quality of finished product chain, reduced operator's labor intensity.
Referring to Fig. 4, increase last die 8 and reached die 9 and the area of contact of encircling a sheet 5 and outer plate 2 down, can reduce the consumption of frock, played the effect of getting twice the result with half the effort.This riveting piece instrument also can be applied with the craft point of various chains and rivet over.Reduce working strength of workers, improved quality of product.The simple and easy to do leveling operation that reduced has been saved frock consumption and a large amount of labor hour.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
